They control the airflow in a targeted way, stop air from being drawn in from unwanted areas and noticeably cut the energy consumption of the entire extraction system. We design every valve for your system and build it at our own plant in St. Veit an der Glan, Austria.  <\/p>\n\n<div class=\"wp-block-rank-math-toc-block\" id=\"rank-math-toc\"><h2>Table of Contents<\/h2><nav><ul><li class=\"\"><a href=\"#so-funktionieren-schnuffelventile\">How sniffle valves work<\/a><\/li><li class=\"\"><a href=\"#ihre-vorteile\">Your benefits<\/a><\/li><li class=\"\"><a href=\"#technische-eckdaten\">Technical specifications<\/a><\/li><li class=\"\"><a href=\"#passendes-zubehor\">Matching accessories<\/a><\/li><li class=\"\"><a href=\"#sie-mochten-ihre-absaugleistung-stabilisieren\">Want to stabilise your suction power?<\/a><\/li><\/ul><\/nav><\/div>\n\n<h2 id=\"so-funktionieren-schnuffelventile\" class=\"wp-block-heading\">How sniffle valves work<\/h2>\n\n<p class=\"wp-block-paragraph\">When individual extraction points in a system are closed, the negative pressure in the ducts rises and the air volume drops. The sniffle valve sits on the duct and, in this situation, lets air in through a grille in a controlled way. An adjustable flap in the housing determines when and how much air flows in. This keeps the air volume and flow velocity in the ducts even, prevents deposits and keeps the fan operating in the right range.   <\/p>\n\n<h2 id=\"ihre-vorteile\" class=\"wp-block-heading\">Your benefits<\/h2>\n\n<ul class=\"wp-block-list\">\n<li><strong>Constant suction:<\/strong> at every extraction point, even when other points are closed.<\/li>\n\n\n\n<li><strong>No unwanted airflows:<\/strong> air is drawn in where intended and in a controlled way.<\/li>\n\n\n\n<li><strong>Less energy:<\/strong> the system runs evenly in its optimum range.<\/li>\n\n\n\n<li><strong>Robust and simple:<\/strong> sturdy housing, perforated grille, adjustable from outside.<\/li>\n<\/ul>\n\n<h2 id=\"technische-eckdaten\" class=\"wp-block-heading\">Key technical data<\/h2>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Feature<\/th><th>Sniffle Valves \/ Leakage Air Valves<\/th><\/tr><\/thead><tbody><tr><td>Loading<\/td><td>control airflow, keep suction power constant<\/td><\/tr><tr><td>Construction<\/td><td>housing with duct connection, perforated grille, adjustable flap<\/td><\/tr><tr><td>Application<\/td><td>central extraction systems with several extraction points<\/td><\/tr><tr><td>Nominal size, connections, materials<\/td><td>designed individually for your system<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<h2 id=\"passendes-zubehor\" class=\"wp-block-heading\">Matching accessories<\/h2>\n\n<p class=\"wp-block-paragraph\">Sniffle valves complement <a href=\"https:\/\/ratec-systems.com\/en\/butterfly-valve\/\">butterfly valves<\/a> and <a href=\"https:\/\/ratec-systems.com\/en\/suction-manifold\/\">intake manifolds<\/a> in <a href=\"https:\/\/ratec-systems.com\/en\/central-vacuum-systems\/\">central vacuum systems<\/a>.
